COAL-OIL BURNER.

SEECIEIOATJLQN forming part of Letters Patent No. 685,407, dated October-29, 1901.

Application filed June 8, 1901 St. Louis, Missouri, haveinvented a new an'duseful Improvement in Goal-Oil Burners and the Like, of which the following is a specifi cation.

My object is to producea coal-oil burner which may readily be placed in cook-stoves,- such as usually burn wood or coal, and which may be used for other similar purposes, and which shall be simple and inexpensive; and my invention consists of the novel features herein shown, described, and claimed.

Figure 1 is a plan of theburner in position for use, parts of the stove being broken away to economize space. Fig. 2 is a front elevation of the burner, parts being broken away and shown in section to better illustrate the construction. Fig.3 is an end elevation of the generator, the other parts being shown in sec tion.

Referring tothe drawings in detail, inthef construction of a burner in accordance with the principles of my invention I employ a mixing-chamber 5 and a generator 6,.placed wholly within the mixing-chamber. The mixing-chamber 5 is a cast-iron trough adapted to fit within the'fire-box of the stove and has draft-inlets? and a smoke-outlet 8. The top 9 of the stove closes the trough. The generator 6 consists of the horizontal portion 10,

which extends along the lower edge of the smoke-outlet 8, the portion 11', which ex tends to the bottom of the mixing-chamber,

the portions 12 13 14 15 16 17, lying one above the other, and the nozzles 18 and 1v9, mounted substantially in the center of the mixing.

chamber and having slits 20 and 21, which" The'generatorj serve as discharge-openings. is formed of a single piece of pipe bent to the form shown, and the nozzles are secured to the discharge ends of the pipe by the T- joint 22. The intermediate portions of the generator occupy a lower central position in the mixing-chamber, so as to bring the nozzles below the'inlets and outlets of the mix ing chamber. The discharge-openings 20 and 21 are so located that the gas is discharged against the top of the stove at such an angle that it rebounds backwardly and downwardly, and this produces a draft, causing fresh air to pass in through the draft-openings and the products of combustion to pass out through the smoke-outlet.

Serial No. 68,697. (No as.)

c When it is desired to start the burner, oil isIallow'ed tdpass through the supply-pipe 23 and through the generator, and it will fall from the nozzles into the bottom of the troughof the mixing-chamber, where it may belighte djand it will then burn up around and heat the generator,'and then theoil may be again turned on and it will be vaporized as it passes through the hot generator and will be discharged as gas, and the gas will burn within the mixing-chamber and keep the generator hot.

If desired, the generator may be made of sections of pipe and elbows or return-bends.

The essentials are a mixing-chamber havinginlet and outlet openings and a generator mounted in the mixing-chamber and having nozzles directed away from the inlet-openings and not directly toward the outlet-openings, so thatthe gas will rebound and heat the generator and draw in air and direct the products of combustion toward the outlet.

I claim-- 1. In a coal-oil burner, a mixing-chamber having inlet and outlet openings, a generator mounted in the mixing-chamber and having nozzles directed a little'fabove the outletopenings and against the stove-top so that the gas will strike the top of the stove and rebound and heat the generator, substantially as specified.

having inlet and outlet openings, and having a bottom to catch oil, a generator mounted in the mixing-chamber and having nozzles directed 'a little above the outlet-openings and against the stove-top so that the gas will strike the top of the stove and rebound and heat the generator, substantially as specified.

3. In a coal-oil burner, a mixing-chamber having inlet and outlet openings and having a bottom to catch oil, a generator mounted in the mixing-chamber so that oil burned in said bottom will heat the generator to start the flow of gas, nozzles on said generator directed a little above the outlet-openings and against the stovetop so that the gas will strike the top of the stove and rebound and heat the generator after it is started, substantially as specified.
